FIG. 2 is a block diagram illustrating an electronic device 101 forcontrolling a handover according to an embodiment of the disclosure.

Referring to FIG. 2, the electronic device 101 may include anapplication processor (AP) 210, communication processors (CP) 220 and230, a display device 240, and a power management module 250. Theapplication processor (AP) 210 may be substantially the same as the mainprocessor 121 of FIG. 1 or may be included in the main processor 121.The communication processors (CPs) 220 and 230 may be substantially thesame as the auxiliary processor 123 (or coprocessor) of FIG. 1 or may beincluded in the auxiliary processor 123 (or coprocessor). The displaydevice 240 may be substantially the same as the display device 160 ofFIG. 1 or may be included in the display device 160. The powermanagement module 250 may be substantially the same as the powermanagement module 188 of FIG. 1 or may be included in the powermanagement module 188.

The application processor 210 may select a network for wirelesscommunication, based on at least one of whether the display device 240is activated, the data throughput of the electronic device 101, whetheran application program associated with a first communication network isexecuted, the state of charge (SoC) of a battery 189, or whether anexternal power source is connected.

When the display device 240 is switched to an inactive state with theelectronic device 101 connected to the first communication network, theapplication processor 210 may control a first communication processor220 and/or a second communication processor 230 to hand over theelectronic device 101 to a second communication network. For example,when the first communication network is configured in a non-standalone(NSA) mode, the application processor 210 may transmit a message forrequesting a handover to the second communication network to the secondcommunication processor 230. The second communication processor 230 mayperform a handover from a first communication network connection stateto a second communication network connection state according to therequest from the application processor 210. Although not shown in thedrawing, the first communication processor 220 and the secondcommunication processor 230 may be connected via a separate interface(e.g., a UART interface or the like) that does not pass through theapplication processor 210. In another example, when the firstcommunication network is configured in a standalone (SA) mode, theapplication processor 210 may transmit a message for requesting ahandover to the second communication network to the first communicationprocessor 220 and the second communication processor 230. For example,when the display device 240 remains in the inactive state for areference time period, the application processor 210 may determine thatthe display device 240 is switched to the inactive state.

When the display device 240 is switched to the inactive state with theelectronic device 101 connected to the first communication network andthe data throughput of the electronic device 101 is lower than areference throughput, the application processor 210 may control thefirst communication processor 220 and/or the second communicationprocessor 230 to hand the electronic device 101 over to the secondcommunication network. For example, the data throughput of theelectronic device 101 may be periodically detected by the applicationprocessor 210 with the display device 240 being in the inactive state.

When the display device 240 is switched to the inactive state with theelectronic device 101 connected to the first communication network andan application program associated with the first communication networkis not executed, the application processor 210 may control the firstcommunication processor 220 and/or the second communication processor230 to hand the electronic device 101 over to the second communicationnetwork. When the application program associated with the firstcommunication network is being executed with the display device 240switched to the inactive state but the data throughput of the electronicdevice 101 is lower than the reference throughput, the applicationprocessor 210 may control the first communication processor 220 and/orthe second communication processor 230 to hand over the electronicdevice 101 to the second communication network. When the applicationprogram associated with the first communication network is beingexecuted with the display device 240 switched to the inactive state andthe data throughput of the electronic device 101 is equal to or higherthan the reference throughput, the application processor 210 may controlthe first communication processor 220 and/or the second communicationprocessor 230 to maintain the connection to the first communicationnetwork.

The application processor 210 may determine whether to perform ahandover to the second communication network, based on at least one ofthe state of charge (SoC level) of the battery 189 or whether anexternal power source is connected when the electronic device 101 isconnected to the first communication network. For example, when thestate of charge (SoC level) of the battery 189 is higher than areference level or an external power source is connected, theapplication processor 210 may determine whether to perform a handover tothe second communication network, based on at least one of whether thedisplay device 240 is active, whether the application program associatedwith the first communication network is executed, or the data throughputof the electronic device 101. For example, when the state of charge (SoClevel) of the battery 189 is lower than the reference level or noexternal power source is connected, the application processor 210 maycontrol the first communication processor 220 and/or the secondcommunication processor 230 to hand over the electronic device 101 tothe second communication network.

When the display device 240 is switched to the active state with theelectronic device 101 handed over to the second communication network,the application processor 210 may control the first communicationprocessor 220 and/or the second communication processor 230 to hand overthe electronic device 101 to the first communication network. Forexample, when the first communication network is configured in thenon-standalone (NSA) mode, the application processor 210 may transmit amessage for requesting a handover to the first communication network tothe second communication processor 230. For example, when the firstcommunication network is configured in the standalone (SA) mode, theapplication processor 210 may transmit a message for requesting ahandover to the first communication network to the first communicationprocessor 220 and the second communication processor 230.

When the display device 240 is switched to the active state with theelectronic device 101 handed over to the second communication networkand the data throughput of the electronic device 101 is equal to orhigher than the reference throughput, the application processor 210 maycontrol the first communication processor 220 and/or the secondcommunication processor 230 to hand over the electronic device 101 tothe first communication network.

When the display device 240 is switched to the active state with theelectronic device 101 handed over to the second communication networkand the application program associated with the first communicationnetwork is executed, the application processor 210 may control the firstcommunication processor 220 and/or the second communication processor230 to hand over the electronic device 101 to the first communicationnetwork.

The application processor 210 may determine whether to perform ahandover to the first communication network, based on at least one ofthe state of charge (SoC level) of the battery 189 or whether anexternal power source is connected. For example, the state of charge(SoC level) of the battery 189 is higher than the reference level or anexternal power source is connected, the application processor 210 maycontrol the first communication processor 220 and/or the secondcommunication processor 230 to perform a handover to the firstcommunication network. For example, when the state of charge (SoC level)of the battery 189 is lower than the reference level or no externalpower source is connected, the application processor 210 may control thefirst communication processor 220 and/or the second communicationprocessor 230 to maintain the connection to the second communicationnetwork.

The application processor 210 may adaptively set reference information(e.g., a reference level, a reference throughput, or the like) forhandover of the electronic device 101, based on a use pattern of eachuser with respect to the electronic device 101. The applicationprocessor 210 may set the use pattern of the user with respect to theelectronic device 101 in view of at least one of data usage per user ofthe electronic device 101, a data throughput, the use frequency of anapplication program, or application program use time collected for acertain time period. The application processor 210 may set (or update)reference information for network switching, based on the use pattern ofthe user with respect to the electronic device 101. The applicationprocessor 210 may transmit at least one of the data usage per user ofthe electronic device 101, the data throughput of the electronic device101, the use frequency of the application program, or the applicationprogram use time collected for the certain time period to a server. Theapplication processor 210 may receive per-user reference information fornetwork switching from the server.

The application processor 210 may adaptively apply the referenceinformation (e.g., the reference level, the reference throughput, or thelike) for the handover of the electronic device 101, based on at leastone of the user, position, or use time point of the electronic device101.

The application processor 210 may detect the data throughput of theelectronic device 101, based on the amount of data (or packet)transmitted and received through the communication processors 220 and230. The first communication processor 220 and the second communicationprocessor 230 may provide the amount of data (or packets) transmittedand received through each communication network to the applicationprocessor 210. The application processor 210 may identify (or estimate)the data throughput of the electronic device 101, based on the amount ofdata transmitted and received through each communication network,provided from the communication processors 220 and 230. For example, theapplication processor 210 may periodically (e.g., every 10 seconds)identify the data throughput of the electronic device 101 with thedisplay device 240 being in the inactive state.

The first communication processor 220 may control transmission andreception of data through the first communication network. The secondcommunication processor 230 may control transmission and reception ofdata through the second communication network. When the firstcommunication network is configured in the non-standalone (NSA) mode,the first communication processor 220 may provide a service through thefirst communication network by interworking with the secondcommunication processor 230. For example, when the electronic device 101wishes to connect to the first communication network, the secondcommunication processor 230 may establish a control channel associatedwith the first communication network through the second communicationnetwork. The first communication processor 220 may establish a datachannel through the first communication network, based on the controlchannel associated with the first communication network establishedthrough the second communication network and may provide a servicethrough the first communication network. When the first communicationnetwork is configured in the standalone (SA) mode, the firstcommunication processor 220 may provide a service through the firstcommunication network alone.

When the first communication network is configured in the standalone(SA) mode, the first communication processor 220 may control the secondcommunication processor 230 to hand over a communication network of theelectronic device 101 according to a handover request from theapplication processor 210. For example, the first communicationprocessor 220 may provide time for a handover to the secondcommunication network to the second communication processor 230, basedon the operating state of the first communication network.

When the application processor 210 determines a handover to the secondcommunication network, based on first state information, the firstcommunication processor 220 may control the second communicationprocessor 230 to perform a handover to the second communication networkat a time when there is no data transmitted and received through thefirst communication network. In one example, when there is no datatransmitted and received through the first communication network at atime of receiving a handover request from the application processor 210,the first communication processor 220 may control the secondcommunication processor 230 to perform a handover to the secondcommunication network. In another example, when there is datatransmitted and received through the first communication network at atime of receiving a handover request from the application processor 210,the first communication processor 220 may delay a handover to the secondcommunication network until transmission and reception of the datathrough the first communication network is completed. When transmissionand reception of the data through the first communication network iscompleted, the first communication processor 220 may control the secondcommunication processor 230 to perform a handover to the secondcommunication network. When there is no data transmitted and receivedthrough the first communication network for a certain time period (e.g.,10 minutes), the first communication processor 220 may control thesecond communication processor 230 to perform a handover to the secondcommunication network. The first communication processor 220 may controltime for the second communication processor 230 to perform a handover tothe second communication network, based on whether there is datatransmitted and received through the first communication network. Forexample, the first state information may include at least one of whetherthe display device 240 is active, an application program being executed,or a data throughput.

When the application processor 210 determines a handover to the secondcommunication network, based on information about the state of charge ofthe battery, the first communication processor 220 may performdisconnection from the first communication network. The firstcommunication processor 220 may perform disconnection from the firstcommunication network, based on a handover request from the applicationprocessor 210, regardless of whether there is data transmitted andreceived through the first communication network. For example, the firstcommunication processor 220 may transmit a disconnection request messageto the first communication network, based on the handover request fromthe application processor 210. When a communication channel with thefirst communication network is released based on the disconnectionrequest message, the first communication processor 220 may transmitinformation about completion of disconnection from the firstcommunication network to the second communication processor 230.

When receiving a message for requesting a handover to the secondcommunication network from the application processor 210, the secondcommunication processor 230 may establish a communication channel withthe second communication network. For example, the application processor210 determines a handover to the second communication network, based onthe first state information, the second communication processor 230 mayestablish a communication channel with the second communication network,based on handover control information provided from the firstcommunication processor 220. The handover control information mayinclude information about time to perform a handover determined based onwhether there is data transmitted/received through the firstcommunication network. For example, when receiving a message forrequesting a handover to the second communication network determinedbased on the state of charge of the battery from the applicationprocessor 210, the second communication processor 230 may establish acommunication channel with the second communication network.

When the first communication network is configured in the non-standalonemode (NSA), the second communication processor 230 may restrict a datachannel request to the first communication network.

When the application processor 210 determines to perform a handover tothe second communication network, based on a first state parameter, thesecond communication processor 230 may restrict a data channel requestto the first communication network at a time when there is no datatransmitted/received through the first communication network. Forexample, when the application processor 210 requests a handover, thesecond communication processor 230 may identify whether there is datatransmitted/received through the first communication network. The secondcommunication processor 230 may identify whether there is datatransmitted/received through the first communication network, by usingthe first communication processor 220. When there is no datatransmitted/received through the first communication network, the secondcommunication processor 230 may control the first communicationprocessor 220 to restrict a data channel request to the firstcommunication network. For example, when there is data transmitted andreceived through the first communication network when the applicationprocessor 210 requests a handover, the second communication processor230 may identify whether data transmission and reception through thefirst communication network is completed. When the data transmission andreception through the first communication network is completed, thesecond communication processor 230 may control the first communicationprocessor 220 to restrict a data channel request to the firstcommunication network. Here, a control channel with the secondcommunication network may be maintained. When there is no datatransmitted and received through the first communication network for acertain time period (e.g., 10 minutes), the second communicationprocessor 230 may control the first communication processor 220 torestrict a data channel request to the first communication network. Forexample, when restricting the data channel request to the firstcommunication network, the second communication processor 230 mayestablish a data channel with the second communication network and maytransmit and receive data through the second communication network(e.g., fall back to the second communication (4G) network).

When the application processor 210 determines to perform a handover tothe second communication network, based on the information about thestate of charge of the battery, the second communication processor 230may control the first communication processor 220 to release the datachannel with the first communication network. The first communicationprocessor 220 may transmit a disconnection request message to the firstcommunication network, based on control of the second communicationprocessor 230. When the data channel with the first communicationnetwork is released, the first communication processor 220 may restricta data channel request to the first communication network. Here, thecontrol channel with the second communication network established usingthe second communication processor 230 may be maintained.

The display device 240 may display information about driving of theelectronic device 101. For example, the display device 240 may beactivated or deactivated based on control of the application processor210. In one example, the display device 240 may provide informationabout an operating state (e.g., an active state or an inactive state) ofthe display device 240 to the application processor 210. The informationabout the operating state may be transmitted periodically or when theoperating state of the display device 240 is changed.

The power management module 250 may provide the information about thestate of charge of the battery 189 to the application processor 210. Forexample, the information about the state of charge of the battery 189may be provided to the application processor 210 periodically or at atime when the charge state level of the battery 189 is changed. Thepower management module 250 may manage charging of the battery 189 usingan external power source connected by at least one of wired or wirelesscharging methods. The power management module 250 may provideinformation about connection of the external power source to theapplication processor 210. The information about the connection of theexternal power source may be provided to the application processor 210when the external power source is connected to the electronic device 101or when the external power source is disconnected.

At least one of the application processor 210 or the communicationprocessors 220 and 230 may be configured as a single chip.

FIG. 3 is a flowchart 300 showing that an electronic device performs ahandover to a second communication network, based on the state of adisplay device and a data throughput according to an embodiment of thedisclosure.

In the following description, individual operations may be performedsequentially but are not necessarily performed sequentially. Forexample, the order of individual operations may be changed, and at leasttwo operations may be performed in parallel. The electronic device maybe the electronic device 101 of FIG. 1 or 2. Hereinafter, at least someoperations of FIG. 3 will be described with reference to FIG. 4.

FIG. 4 illustrates a screen configuration for displaying informationabout a handover to a second communication network in an electronicdevice according to an embodiment of the disclosure.

Referring to FIG. 3, in operation 301, the electronic device (e.g., theprocessor 120 and/or the wireless communication module 192 of FIG. 1)may connect to a first communication network (e.g., a 5G network) andmay transmit and receive data through the first communication network.When the electric field intensity (e.g., a received signal strengthindication (RSSI)) of the first communication network is equal to orhigher than a reference electric field strength, the processor 120(e.g., the application processor 210 of FIG. 2) may be connected to thefirst communication network through the wireless communication module192 to transmit and receive data.

In operation 303, the electronic device (e.g., the processor 120) maydetermine whether to perform a handover to a second communicationnetwork, based on whether the display device 160 is activated and a datathroughput. When the display device 160 is switched to the inactivestate and the data throughput is lower than a reference throughput, theprocessor 120 may determine to perform a handover to the secondcommunication network. When the display device 160 is in the activestate or the data throughput is higher than the reference throughput,the processor 120 may determine to maintain the connection to the firstcommunication network.

In operation 305, the electronic device (e.g., the processor 120) mayidentify whether it is determined to perform a handover to the secondcommunication network, based on whether the display device 160 isactivated and the data throughput. When it is determined to maintain theconnection to the first communication network (e.g., No in operation305), the electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may maintain the connection to the firstcommunication network.

When it is determined to perform a handover to the second communicationnetwork (e.g., a 4G network) (e.g., Yes in operation 305), theelectronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may perform the handover to the secondcommunication network in operation 307. When it is determined to performa handover to the second communication network, based on whether thedisplay device 160 is activated and the data throughput, the processor120 may identify the channel state (e.g., electric field intensity) ofat least one second communication network adjacent to the electronicdevice 101. The processor 120 may perform a handover to a secondcommunication network that is equal to or higher than a referenceelectric field intensity. In one example, when there is a plurality ofsecond communication networks having an electric field intensity equalto or higher than the reference electric field, the processor 120 mayperform a handover to a second communication network having the highestelectric field intensity.

When it is determined to perform the handover to the secondcommunication network (e.g., the 4G network), the processor 120 mayindicate the handover to the second communication network to thewireless communication module 192. When the handover to the secondcommunication network is indicated, the wireless communication module192 may identify whether there is data transmitted and received throughthe first communication network. When there is no data transmitted andreceived through the first communication network, the wirelesscommunication module 192 may perform a handover to the secondcommunication network. When there is data transmitted and receivedthrough the first communication network, the wireless communicationmodule 192 may perform a handover to the second communication networkafter completing transmission and reception of the data using the firstcommunication network. For example, when there is no data transmittedand received through the first communication network for a certain timeperiod (e.g., 10 seconds), the wireless communication module 192 (e.g.,the first CP 220 or the second CP 230) may perform a handover to thesecond communication network.

When an input to select an Accept menu 402 isdetected, the processor 120 may perform a handover to the secondcommunication network. When an input to select a Reject menu 404 isdetected, the processor 120 may determine that the user of theelectronic device 101 does not want a handover to the secondcommunication network. Accordingly, the processor 120 may maintain theconnection to the first communication network. When inputs to select theAccept menu 402 and the Reject menu 404 are not detected for a referencetime period, the processor 120 may perform a handover to the secondcommunication network.

FIG. 5 is a flowchart showing that an electronic device determineswhether to perform a handover, based on the state of a display deviceand a data throughput according to an embodiment of the disclosure.

The following operations of FIG. 5 may be detailed operations ofoperation 303 of FIG. 3. In the following embodiments, individualoperations may be performed sequentially but are not necessarilyperformed sequentially. For example, the order of individual operationsmay be changed, and at least two operations may be performed inparallel. Here, the electronic device may be the electronic device 101of FIG. 1 or 2.

Referring to FIG. 5, in operation 501, the electronic device (e.g., theprocessor 120 of FIG. 1) may determine whether the display device 160 isswitched to the inactive state. When the electronic device 101 isconnected to a first communication network (e.g., an NR network) (e.g.,operation 301 of FIG. 3), the processor 120 (e.g., the applicationprocessor 210 of FIG. 2) may identify whether the display device 160remains in the inactive state for a reference time period. When thedisplay device 160 remains in the inactive state for the reference timeperiod, the processor 120 may determine that the display device 160 isswitched to the inactive state.

When the display device 160 is switched to the inactive state (e.g., Yesin operation 501), the electronic device (e.g., the processor 120) mayidentify whether the data throughput of the electronic device is lowerthan a reference throughput in operation 503. When the display device160 is switched to the inactive state, the processor 120 mayperiodically determine the data throughput of the electronic device 101,based on the amount of data transmitted and received through a wirelesscommunication module 192.

When the data throughput of the electronic device is lower than thereference throughput (e.g., Yes in operation 503), the electronic device(e.g., the processor 120 and/or the wireless communication module 192)may determine to hand over a communication network to a secondcommunication network (e.g., an LTE network) in operation 505. When thedisplay device 160 is switched to the inactive state and the datathroughput is lower than the reference throughput, the processor 120 mayidentify the electric field intensities of second communication networksadjacent to the electronic device 101. Among the second communicationnetworks adjacent to the electronic device 101, a second communicationnetwork having an electric field intensity equal to or higher than areference electric field strength may be selected as a network to whichthe electronic device 101 performs a handover.

When the display device 160 remains in the active state (e.g., No inoperation 501) or the data throughput of the electronic device is equalto or higher than the reference throughput (e.g., No in operation 503),the electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may determine to maintain the connection tothe first communication network in operation 507. The wirelesscommunication module 192 may transmit and receive data through the firstcommunication network.

When the connection to the first communication network is maintainedwith the display device 160 being in the inactive state, the processor120 may periodically identify the data throughput of the electronicdevice 101. When the data throughput of the electronic device 101 islower than the reference throughput with the display device 160 being inthe inactive state, the processor 120 may control the wirelesscommunication module 192 to perform a handover to the secondcommunication network.

The following operations of FIG. 6 may be detailed operations ofoperation 303 of FIG. 3. In the following embodiments, individualoperations may be performed sequentially but are not necessarilyperformed sequentially. For example, the order of individual operationsmay be changed, and at least two operations may be performed inparallel. Here, the electronic device may be the electronic device 101of FIG. 1 or 2.

Referring to FIG. 6, in operation 601, the electronic device (e.g., theprocessor 120 of FIG. 1) may identify whether the display device 160 isswitched to the inactive state with the electronic device 101 connectedto a first communication network (e.g., a 5G network) (e.g., operation301 of FIG. 3). For example, a switch of the display device 160 to theinactive state may include a state in which the display device 160remains in the inactive state for a reference time period.

When the display device 160 is switched to the inactive state (e.g., Yesin operation 601), the electronic device (e.g., the processor 120) mayidentify whether an application program associated with the firstcommunication network is being executed in operation 603. For example,the application program associated with the first communication networkmay include at least one application program that provides a serviceusing the first communication network.

When the application program associated with the first communicationnetwork is being executed (e.g., Yes in operation 603), the electronicdevice (e.g., the processor 120) may identify whether the datathroughput of the electronic device is lower than a reference throughputin operation 605. For example, the data throughput of the electronicdevice 101 may be determined based on the amount of data transmitted andreceived through a wireless communication module 192 for a referencetime period in a case that the display device 160 is switched to theinactive state.

When the application program associated with the first communicationnetwork is not being executed (e.g., No in operation 603) or the datathroughput of the electronic device is lower than the referencethroughput (e.g., Yes in operation 605), the electronic device (e.g.,the processor 120 and/or the wireless communication module 192) maydetermine to hand over a communication network to a second communicationnetwork (e.g., an LTE network) in operation 607. For example, the secondcommunication network to which the electronic device 101 is handed overmay include an LTE network having an electric field intensity equal toor higher than a reference electric field strength.

When the display device 160 remains in the active state (e.g., No inoperation 601) or the data throughput of the electronic device is equalto or higher than the reference throughput (e.g., No in operation 605),the electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may determine to maintain the connection tothe first communication network in operation 609.

When the connection to the first communication network is maintainedbased on execution of the application program associated with the firstcommunication network with the display device 160 being in the inactivestate, the processor 120 may periodically identify the data throughputof the electronic device 101. When the data throughput of the electronicdevice 101 is lower than the reference throughput with the displaydevice 160 being in the inactive state, the processor 120 may controlthe wireless communication module 192 to perform a handover to thesecond communication network.

Hereinafter, at leastsome operations of FIG. 7 will be described with reference to FIG. 8.

FIG. 8 illustrates the screen configuration of a handover setting menuconsidering a battery charge state in an electronic device according toan embodiment of the disclosure.

Referring to FIGS. 7 and 8, in operation 701, the electronic device(e.g., the processor 120 and/or the wireless communication module 192 ofFIG. 1) may transmit and receive data through a first communicationnetwork (e.g., an NR network). The wireless communication module 192 mayconnect to the first communication network having an electric fieldintensity equal to or higher than a reference electric field strength totransmit and receive the data.

In operation 703, the electronic device (e.g., the processor 120 and/orthe power management module 188) may identify whether the charge statelevel (SoC level) of a battery is equal to or greater than a referencelevel. For example, the charge state level of the battery may bereported by the power management module 188 to the processor 120periodically or when the charge state level of the battery is changed.

When the charge state level (SoC level) of the battery is equal to orgreater than the reference level (e.g., Yes in operation 703), theelectronic device (e.g., the processor 120) may determine whether toperform a handover to a second communication network, based on whetherthe display device 160 is activated and a data throughput, in operation705. As shown in operations 501 to 507 of FIG. 5, the processor 120(e.g., the application processor 210 of FIG. 2) may determine whether toperform a handover to the second communication network, based on whetherthe display device 160 is activated and the data throughput. As shown inoperations 601 to 609 of FIG. 6, the processor 120 (e.g., theapplication processor 210 of FIG. 2) may determine whether to perform ahandover to the second communication network, based on whether thedisplay device 160 is activated, whether an application programassociated with the first communication network is executed, and thedata throughput.

In operation 707, the electronic device (e.g., the processor 120) mayidentify whether it is determined to perform a handover to the secondcommunication network, based on whether the display device 160 isactivated and the data throughput. When the display device 160 isswitched to the inactive state and the data throughput is lower than areference throughput, the processor 120 may determine to perform ahandover to the second communication network. When the display device160 is switched to the inactive state and the application programassociated with the first communication network is executed but the datathroughput is lower than the reference throughput, the processor 120determines to perform a handover to the second communication network.

When it is determined not to perform a handover to the secondcommunication network in operation 705 (e.g., No in operation 707), theelectronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may maintain the connection to the firstcommunication network.

When the charge state level (SoC level) of the battery is lower than thereference level (e.g., No in operation 703) or it is determined toperform a handover to the second communication network (e.g., Yes inoperation 707), the electronic device (e.g., the processor 120 and/orthe wireless communication module 192) may perform a handover to thesecond communication network in operation 709. The processor 120 mayprovide a request for a handover to the second communication network tothe wireless communication module 192. The wireless communication module192 may perform a handover to the second communication network having anelectric field intensity equal to or higher than the reference electricfield strength. When determining the handover to the secondcommunication network, based on the charge state of the battery, theprocessor 120 may transmit a handover request message to the firstcommunication network. When determining the handover to the secondcommunication network, based on the charge state of the battery, theprocessor 120 may control the wireless communication module 192 toperform a handover to the second communication network regardless ofwhether there is data transmitted and received through the firstcommunication network. In one example, the processor 120 may provideinformation related to a parameter (e.g., first state information orcharge state information about the battery) considered in determiningthe handover to the second communication network to the wirelesscommunication module 192. For example, the processor 120 may addparameter information to the handover request message, may configure thehandover request message in a different form to correspond to theparameter, or may transmit the parameter information using a separatemessage.

When the electronic device 101 is connected to anexternal power source and is supplied with power from the external powersource, the processor 120 (e.g., the application processor 210 of FIG.2) may determine whether to perform a handover to the secondcommunication network, based on whether the display device 160 isactivated and the data throughput as shown in operations 501 to 507 ofFIG. 5. When the electronic device 101 is connected to an external powersource and is supplied with power from the external power source, theprocessor 120 (e.g., the application processor 210 of FIG. 2) maydetermine whether to perform a handover to the second communicationnetwork, based on whether the display device 160 is activated, whetheran application program associated with the first communication networkis executed, and the data throughput as shown in operations 601 to 609of FIG. 6. When the electronic device 101 is not connected to anexternal power source, the processor 120 (e.g., the applicationprocessor 210 of FIG. 2) may determine whether to perform a handover tothe second communication network, based on the charge state level of thebattery as shown in operations 701 to 709 of FIG. 7.

The following operations of FIG. 15 may be detailed operations ofoperation 1407 of FIG. 14. In the following embodiments, individualoperations may be performed sequentially but are not necessarilyperformed sequentially. For example, the order of individual operationsmay be changed, and at least two operations may be performed inparallel. Here, the electronic device may be the electronic device 101of FIG. 1 or 2.

Referring to FIG. 15, when it is determined to perform a handover to thesecond communication network (e.g., Yes in operation 1405 of FIG. 14),the electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192 of FIG. 1) may identify whether there is datatransmitted and received through a first communication network inoperation 1501. The wireless communication module 192 may identifywhether there is data transmitted and received through a data channelwith the first communication network.

When there is data transmitted and received through the firstcommunication network (e.g., Yes in operation 1501), the electronicdevice (e.g., the processor 120 and/or the wireless communication module192) may identify whether transmission and reception of the data throughthe first communication network is completed in operation 1503.

When transmission and reception of the data through the firstcommunication network is not completed (e.g., No in operation 1503), theelectronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may identify whether transmission andreception of the data through the first communication network iscompleted. The processor 120 (e.g., the application processor 210 ofFIG. 2) may periodically identify whether transmission and reception ofthe data through the first communication network is completed.

When there is no data transmitted and received through the firstcommunication network (e.g., No in operation 1501) or transmission andreception of the data through the first communication network iscompleted (e.g., Yes in operation 1503), the electronic device (e.g.,the processor 120 and/or the wireless communication module 192) mayrestrict a data channel request to the first communication network inoperation 1505.

In the following embodiments, individual operations may be performedsequentially but are not necessarily performed sequentially. Forexample, the order of individual operations may be changed, and at leasttwo operations may be performed in parallel. Here, the electronic devicemay be the electronic device 101 of FIG. 1 or 2.

Referring to FIG. 16, in operation 1601, the electronic device (e.g.,the processor 120 and/or the wireless communication module 192 ofFIG. 1) may connect to the first communication network (e.g. a 5Gnetwork) using the second communication network (e.g., an LTE network).When the first communication network is configured in the non-standalone(NSA) mode, the wireless communication module 192 may establish a datachannel with the first communication network, based on controlinformation obtained through the second communication network.

In operation 1603, the electronic device (e.g., the processor 120 and/orthe power management module 188) may identify whether the charge statelevel (SoC) of a battery is less than a reference level. The powermanagement module 188 may provide charge state information about thebattery to the processor 120 (e.g., the application processor 210 ofFIG. 2) periodically or when the charge state level of the battery ischanged.

When the charge state level (SoC) of the battery is less than thereference level (e.g., Yes in operation 1603), the electronic device(e.g., the processor 120 and/or the power management module 188) mayidentify whether an external power source is connected in operation1605. The power management module 188 may identify whether power issupplied from an external power source that is connected to theelectronic device 101 via a cable or wirelessly.

When no external power source is connected (e.g., No in operation 1605),the electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may transmit a disconnection message to thefirst communication network in operation 1607. When the charge statelevel of the battery is less than the reference level and no externalpower source is connected, the processor 120 may determine to perform ahandover to the second communication network. The processor 120 maycontrol the wireless communication module 192 to transmit thedisconnection message in order to release the data channel with thefirst communication network.

The electronic device (e.g., the processor 120 and/or the wirelesscommunication module 192) may be disconnected from the firstcommunication network in operation 1609. When receiving a responsemessage (e.g., an ACK signal) to the disconnection message from thefirst communication network, the processor 120 may release the datachannel with the first communication network. The wireless communicationmodule 192 may transmit and receive data through a communication channelwith a preset second communication network in order to connect to thefirst communication network.

In operation 1611, the electronic device (e.g., the processor 120 and/orthe wireless communication module 192) may restrict a data channelrequest to the first communication network. For example, when dataassociated with the electronic device 101 occurs in a case that the datachannel with the first communication network is disconnected, theprocessor 120 does not transmit a request message for establishing adata channel to the first communication network. In this case, thewireless communication module 192 may transmit and receive the dataassociated with the electronic device 101 through the communicationchannel with the second communication network.

When the charge state level (SoC level) of the battery is equal to orgreater than the reference level (e.g., No in operation 1603) or anexternal power source is connected (e.g., Yes in operation 1605), theelectronic device (e.g., the processor 120) may determine whether toperform a handover to the second communication network, based on whetherthe display device 160 is activated and a data throughput. The processor120 may determine whether to perform a handover to the secondcommunication network, based on whether the display device 160 isactivated and the data throughput, as shown in operations 501 to 507 ofFIG. 5. The processor 120 may determine whether to perform a handover tothe second communication network, based on whether the display device160 is activated, whether an application program associated with thefirst communication network is executed, and the data throughput, asshown in operations 601 to 609 of FIG. 6.

In the following embodiments, individual operations may be performedsequentially but are not necessarily performed sequentially. Forexample, the order of individual operations may be changed, and at leasttwo operations may be performed in parallel. Here, the electronic devicemay be the electronic device 101 of FIG. 1 or 2.

Referring to FIG. 17, In operation 1701, the electronic device (e.g.,the processor 120 of FIG. 1) may collect usage information about theelectronic device. For example, the usage information about theelectronic device may include at least one of data usage per user of theelectronic device 101, a data throughput, the use frequency of anapplication program, or application program use time.

In operation 1703, the electronic device (e.g., the processor 120) maydetermine a use pattern of a user with respect to the electronic device,based on the usage information about the electronic device. For example,the use pattern may include at least one of the use frequency, the usetime point, or the use time of a service associated with a firstcommunication network. The electronic device may include a numericprocessing unit (NPU) to analyze the usage information about theelectronic device and to determine the use pattern of the user withrespect to the electronic device.

In operation 1705, the electronic device (e.g., the processor 120) mayset reference information associated with a handover, based on the usepattern. The frequency of the user using the service associated with thefirst communication network is relatively high, the processor 120 (e.g.,the application processor 210 of FIG. 2) may set the referenceinformation associated with the handover such that the frequency of ahandover to a second communication network is reduced. When thefrequency of the user using the service associated with the firstcommunication network is relatively low, the processor 120 may set thereference information associated with the handover such that a handoverto the second communication network relatively easily occurs. In oneexample, the processor 120 may set the reference information associatedwith the handover, based on the position or use time point of theelectronic device 101. The reference information associated with thehandover may include, for example, at least one of a reference level forcomparison with the charge state level of a battery, a referencethroughput for comparison with a data throughput, or a reference timeperiod for identifying whether the display device 160 is in the inactivestate.

In operation 1707, the electronic device (e.g., the processor 120) mayidentify whether the reference information associated with the handoverhas been changed. The processor 120 may identify whether the referenceinformation associated with the handover set in operation 1705 is thesame as reference information associated with a handover stored in thememory 130.

When the reference information associated with the handover has beenchanged (e.g., Yes in operation 1707), the electronic device (e.g., theprocessor 120) may update the reference information associated with thehandover, previously set in the electronic device, to the referenceinformation associated with the handover corresponding to the usepattern of the user in operation 1709. In one example, the referenceinformation associated with the handover may be stored in a table form.

The electronic device may transmit the usage information about theelectronic device to a server. The electronic device may update thereference information stored in the electronic device, based onreference information associated with a handover provided from theserver.

The electronic device may set reference information associated with ahandover, based on a user input. The processor 120 may set referenceinformation associated with a handover, based on a user input to areference information setting menu.

The electronic device may selectively collect the usage informationabout the electronic device, based on a user's setting. When the userenables usage information collection, the electronic device may collectthe usage information about the electronic device.

When it is determined that the usage information about the electronicdevice cannot be collected or the collected usage information isunreliable, the electronic device may determine whether to perform ahandover to the second communication network using predefined referenceinformation associated with a handover. For example, the predefinedreference information associated with the handover may include at leastone of previously set reference information or initial referenceinformation set in the electronic device 101.

The electronic device 101 may selectively perform a handover to reducepower consumption due to wireless communication, based on a user input.An operation of selectively performing a handover is described belowwith reference to FIG. 18 or FIG. 19.

FIG. 18 illustrates the screen configuration of a network mode settingmenu in an electronic device according to an embodiment of thedisclosure.

Referring to FIG. 18, according to an embodiment, the electronic device101 may provide a network mode menu 1802 for selecting a network forwireless communication in a menu 1800 for managing a network forwireless communication. When detecting an input to select the networkmode menu 1802, the electronic device 101 may display a network list1810 through at least a portion of a display device 160. For example, anLTE mode 1812 may include a mode in which the electronic device 101preferentially connects to an LTE network among supportable networks. AnLTE switch mode 1814 may include a mode of handing over a network forwireless communication to reduce power consumption due to wirelesscommunication. A 5G/LTE mode 1816 may include a mode in which theelectronic device 101 preferentially connects to a 5G network (NRnetwork) among supportable networks.

When the LTE switch mode 1814 is selected from the network list 1810,the electronic device 101 may hand over a network for wirelesscommunication, based on at least one of whether the display device 160is activated, a data throughput, whether an application programassociated with a first communication network is executed, the chargestate (SoC) of a battery 189, or whether an external power source isconnected. For example, when the LTE switch mode 1814 is selected, theelectronic device 101 may hand over the network, based on operations 301to 307 of FIG. 3.

When the LTE switch mode 1814 is not selected from the network list1810, the electronic device 101 may determine that a handover forreducing power consumption due to wireless communication is restricted.For example, when the LTE switch mode 1814 is not selected, theelectronic device 101 may restrict an operation of handing over anetwork according to operations 301 to 307 of FIG. 3.

FIG. 19 illustrates the screen configuration of a network switching menuin an electronic device according to an embodiment of the disclosure.

Referring to FIG. 19, the electronic device 101 may provide an LTEswitch setup menu 1902 for setting whether to activate an LTE switchmode in a menu 1900 for managing a network for wireless communication.For example, the LTE switch mode may include a mode of handing over anetwork for wireless communication to reduce power consumption due towireless communication.

When the LTE switch setup menu 1902 is set in an inactive state, theelectronic device 101 may determine that a handover for reducing powerconsumption due to wireless communication is restricted.

When the LTE switch setup menu 1902 is set in an active state, theelectronic device 101 may hand over a network for wirelesscommunication, based on at least one of whether a display device 160 isactivated, a data throughput, whether an application program associatedwith a first communication network is executed, the charge state (SoC)of a battery 189, or whether an external power source is connected. Forexample, when the electronic device 101 performs a handover to a secondcommunication network (LTE mode), based on the charge state of thebattery 189 while connected to the first communication network, theelectronic device 101 may display information 1912 about the handover tothe second communication network (e.g., ‘The device has been switched toLTE for power saving’) on the display device 160 (1910). For example,the information 1912 about the handover to the second communicationnetwork may be deleted from the display device 160 after a lapse of acertain time period or when a user input is detected.

According to various embodiments of the disclosure, an operating methodof an electronic device 101 may include connecting to a firstcommunication network among a plurality of communication networkssupportable by the electronic device 101; determining whether to performa handover to a second communication network, based on whether a displaydevice 160 is activated and a data throughput, in a state of connectionto the first communication network; and performing a handover to thesecond communication network when it is determined to perform thehandover to the second communication network.

The determining whether to perform the handover may include determiningto perform the handover to the second communication network when thedisplay device 160 is deactivated and the data throughput is lower thana reference throughput.

The reference throughput may be set based on a use pattern of a userwith respect to the electronic device 101, and the use pattern may beset based on at least one of a data usage per user collected for areference time period, the data throughput, a use frequency of anapplication program, or an application program use time.

The determining whether to perform the handover may include determiningto perform the handover to the second communication network when thedisplay device 160 is deactivated and an application processorassociated with the first communication network is not driven; anddetermining to perform the handover to the second communication networkwhen the display device 160 is deactivated, the application processorassociated with the first communication network is driven, and the datathroughput is lower than the reference throughput

The performing of the handover may include: identifying whether there isdata transmitted and received through the first communication networkwhen it is determined to perform the handover to the secondcommunication network; identifying whether transmission and reception ofdata through the first communication network is completed when there isthe data transmitted and received through the first communicationnetwork; and performing the handover to the second communication networkwhen the transmission and reception of the data through the firstcommunication network is completed.

The method may further include identifying a state of charge (SoC) of abattery 189; and performing the handover to the second communicationnetwork when the SoC of the battery 189 is lower than a reference level.

The determining whether to perform the handover may include determiningwhether to perform the handover to the second communication network,based on whether the display device is activated and the datathroughput, when the SoC of the battery 189 is equal to or higher thanthe reference level.

The method may further include identifying whether the display device isactivated when the handover to the second communication network isperformed; and performing a handover to the first communication networkwhen the display device is activated.
